Substance Use, Violence, and Antiretroviral Adherence: A Latent Class Analysis of Women Living with HIV in Canada

We used latent class analysis to identify substance use patterns for 1363 women living with HIV in Canada and assessed associations with socio-economic marginalization, violence, and sub-optimal adherence to combination antiretroviral therapy (cART). A six-class model was identified consisting of: abstainers (26.3%), Tobacco Users (8.81%), Alcohol Users (31.9%), ‘Socially Acceptable’ Poly-substance Users (13.9%), Illicit Poly-substance Users (9.81%) and Illicit Poly-substance Users of All Types (9.27%). Multinomial logistic regression showed that women experiencing recent violence had significantly higher odds of membership in all substance use latent classes, relative to Abstainers, while those reporting sub-optimal cART adherence had higher odds of being members of the poly-substance use classes only. Factors significantly associated with Illicit Poly-substance Users of All Types were sexual minority status, lower income, and lower resiliency. Findings underline a need for increased social and structural supports for women who use substances to support them in leading safe and healthy lives with HIV.

Pregnancy incidence and intention after HIV diagnosis among women living with HIV in Canada

Background Pregnancy incidence rates among women living with HIV (WLWH) have increased over time due to longer life expectancy, improved health status, and improved access to and HIV prevention benefits of combination antiretroviral therapy (cART). However, it is unclear whether intended or unintended pregnancies are contributing to observed increases. Methods We analyzed retrospective data from the Canadian HIV Women’s Sexual and Reproductive Health Cohort Study (CHIWOS). Kaplan-Meier methods and GEE Poisson models were used to measure cumulative incidence and incidence rate of pregnancy after HIV diagnosis overall, and by pregnancy intention. We used multivariable logistic regression models to examine independent correlates of unintended pregnancy among the most recent/current pregnancy. Results Of 1,165 WLWH included in this analysis, 278 (23.9%) women reported 492 pregnancies after HIV diagnosis, 60.8% of which were unintended. Unintended pregnancy incidence (24.6 per 1,000 Women-Years (WYs); 95% CI: 21.0, 28.7) was higher than intended pregnancy incidence (16.6 per 1,000 WYs; 95% CI: 13.8, 20.1) (Rate Ratio: 1.5, 95% CI: 1.2–1.8). Pregnancy incidence among WLWH who initiated cART before or during pregnancy (29.1 per 1000 WYs with 95% CI: 25.1, 33.8) was higher than among WLWH not on cART during pregnancy (11.9 per 1000 WYs; 95% CI: 9.5, 14.9) (Rate Ratio: 2.4, 95% CI: 2.0–3.0). Women with current or recent unintended pregnancy (vs. intended pregnancy) had higher adjusted odds of being single (AOR: 1.94; 95% CI: 1.10, 3.42), younger at time of conception (AOR: 0.95 per year increase, 95% CI: 0.90, 0.99), and being born in Canada (AOR: 2.76, 95% CI: 1.55, 4.92). Conclusion Nearly one-quarter of women reported pregnancy after HIV diagnosis, with 61% of all pregnancies reported as unintended. Integrated HIV and reproductive health care programming is required to better support WLWH to optimize pregnancy planning and outcomes and to prevent unintended pregnancy.

Condomless Sex Among Virally Suppressed Women With Hiv With Regular Hiv-serodiscordant Sexual Partners in the Era of Treatment as Prevention

Background: Sexual HIV transmission does not occur with sustained undetectable viral load (VL) on antiretroviral therapy (ART). Awareness of ART prevention benefits and its influence on condom use among women with HIV (WWH) remain unexplored. We estimated prevalence and correlates of condomless sex with regular HIV-serodiscordant partners among WWH with undetectable VL on ART. Methods: We used baseline questionnaire data from the community-based longitudinal Canadian HIV Womens Sexual and Reproductive Health Cohort Study (CHIWOS). We included WWH self-reporting vaginal/anal sex with ≥1 HIV-negative/unknown status regular partner within 6 months, and undetectable VL (<50 copies/mL) on ART. We excluded participants exclusively reporting female partners or missing condom-use data. Condomless sex was defined as <100% condom use within 6 months. The primary explanatory variable was awareness of ART prevention benefits. Logistic regression identified factors independently associated with condomless sex. Results: Of 271 participants (19% of the CHIWOS cohort), median age was 41 (interquartile range: 34–47), 51% were in a relationship, 55% reported condomless sex, and 75% were aware of ART prevention benefits. Among women aware, 63% reported condomless sex compared with 32% of women not aware (P < 0.001). Factors independently associated with condomless sex included being aware of ART prevention benefits (adjusted odds ratio: 4.08; 95% confidence interval: 2.04 to 8.16), white ethnicity, ≥high-school education, residing in British Columbia, and being in a relationship. Conclusions: Virally suppressed women aware of ART prevention benefits had 4-fold greater odds of condomless sex. Advancing safer sex discussions beyond condoms is critical to support women in regular serodiscordant partnerships to realize options for safe and satisfying sexuality in the Treatment-as-Prevention era.

Factors Associated with the Separate and Concurrent Experiences of Food and Housing Insecurity Among Women Living with HIV in Canada

People living with HIV are disproportionately affected by food and housing insecurity. We assessed factors associated with experiencing food and/or housing insecurity among women living with HIV (WLHIV) in Canada. In our sample of WLHIV (N = 1403) 65% reported an income less than

High rates of posttraumatic stress symptoms in women living with HIV in Canada

20,000 per year. Most (78.69%) participants reported food and/or housing insecurity: 27.16% reported experiencing food insecurity alone, 14.26% reported housing insecurity alone, and 37.28% reported experiencing food and housing insecurity concurrently. In adjusted multivariable logistic regression analyses, experiencing concurrent food and housing insecurity was associated with: lower income, Black ethnicity versus White, province of residence, current injection drug use, lower resilience, HIV-related stigma, and racial discrimination. Findings underscore the urgent need for health professionals to assess for food and housing insecurity, to address the root causes of poverty, and for federal policy to allocate resources to ameliorate economic insecurity for WLHIV in Canada.

Supporting The Sexual Rights of Women Living With HIV: A Critical Analysis of Sexual Satisfaction and Pleasure Across Five Relationship Types

Purpose Women living with HIV experience high levels of trauma exposure before and after diagnosis. One of the most challenging outcomes following trauma exposure is posttraumatic stress disorder. Despite high exposure to traumatic events, the presence and contributors to posttraumatic stress disorder symptoms have not been examined in women living with HIV in Canada. Methods The current study examines the presence of, contributors to, and geographical regions associated with self-reported posttraumatic stress symptoms (PTSS) among 1405 women enrolled in the Canadian HIV Women’s Sexual & Reproductive Health Cohort Study (CHIWOS). Results Separate linear regression models were run for the three provinces in the cohort: British Columbia, Ontario and Québec. Scores consistent with posttraumatic stress disorder were reported by 55.9%, 39.1% and 54.1% of the participants in each province, respectively (F(2, 1402) = 13.53, p < .001). Conclusions The results demonstrate that women living with HIV have high rates of PTSS, and that rates and variables associated with these symptoms vary by province. These results suggest the need for trauma-informed practices and care for women living with HIV in Canada, which may need to be tailored for the community and identities of the women.

The importance of sex in the lives of women living with HIV: A critical quantitative analysis

In the context of human immunodeficiency virus (HIV), a focus on protecting others has overridden concern about women’s own sexual well-being. Drawing on feminist theories, we measured sexual satisfaction and pleasure across five relationship types among women living with HIV in Canada. Of the 1,230 women surveyed, 38.1% were completely or very satisfied with their sexual lives, while 31.0% and 30.9% were reasonably or not very/not at all satisfied, respectively. Among those reporting recent sexual experiences (n = 675), 41.3% always felt pleasure, with the rest reporting usually/sometimes (38.7%) or seldom/not at all (20.0%). Sex did not equate with satisfaction or pleasure, as some women were completely satisfied without sex, while others were having sex without reporting pleasure. After adjusting for confounding factors, such as education, violence, depression, sex work, antiretroviral therapy, and provider discussions about transmission risk, women in long-term/happy relationships (characterized by higher levels of love, greater physical and emotional intimacy, more equitable relationship power, and mainly HIV-negative partners) had increased odds of sexual satisfaction and pleasure relative to women in all other relational contexts. Those in relationships without sex also reported higher satisfaction ratings than women in some sexual relationships. Findings put focus on women’s rights, which are critical to overall well-being.

HIV-related stigma, racial discrimination, and gender discrimination: Pathways to physical and mental health-related quality of life among a national cohort of women living with HIV

ABSTRACT The authors explored the importance of sex for 1,289 women living with HIV in Canada. Approximately half of women viewed sex as “very” (19.6%) or “somewhat” important (32.3%) and the remaining reported “neither important or unimportant” (22.0%), “somewhat unimportant” (5.4%), or “not at all important” (20.1%). Women who had a regular sex partner, identified as African, Caribbean, or Black, were more educated, believed HIV treatment prevents transmission, or had better physical health-related quality-of-life reported greater importance of sex, whereas those who were older, used illicit drugs, or experienced violence in adulthood reported lesser importance. Findings underscore the diversity of womens perspectives within the context of their lives.

Contraceptive Choice and Use of Dual Protection Among Women Living with HIV in Canada: Priorities for Integrated Care

Social inequities compromise health-related quality of life (HR-QoL) among women living with HIV (WLWH). Little is known about health impacts of intersecting stigma based on HIV status, race and gender among WLWH or potential mechanisms to promote HR-QoL. We tested pathways from multiple types of stigma (HIV-related, racial, gender) to physical and mental HR-QoL utilizing baseline survey data from a national cohort of WLWH in Canada (2013-2015). Structural equation modeling was conducted using maximum likelihood estimation methods to test the direct effects of HIV-related stigma, racial discrimination, and gender discrimination on HR-QoL and indirect effects via social support and economic insecurity, adjusting for socio-demographic factors. Among 1425 WLWH (median age: 43years [IQR=35-50]), HIV-related stigma and gender discrimination had significant direct effects on mental HR-QoL. Social support mediated the relationship between HIV-related stigma and mental HR-QoL, accounting for 22.7% of the effect. Social support accounted for 41.4% of the effect of gender discrimination on mental HR-QoL. Economic insecurity accounted for 14.3% of the effect of HIV-related stigma, and 42.4% of the effect of racial discrimination, on physical HR-QoL. Fit indices suggest good model fit (χ2[1]=3.319, p=0.069; CFI=0.998; RMSEA=0.042 (90% CI: 0-0.069); SRMR=0.004). Findings reveal complex relationships between intersecting stigma and HR-QoL. Strategies that address intersecting stigma and economic insecurity among WLWH may prevent the harmful impacts of HIV-related stigma and gender discrimination on physical HR-QoL. Increasing social support may mitigate the impacts of stigma on mental health. Findings can inform multi-level interventions to promote health and wellbeing among WLWH.

Validating a self-report measure of HIV viral suppression: an analysis of linked questionnaire and clinical data from the Canadian HIV Women’s Sexual and Reproductive Health Cohort Study

CONTEXT Preventing unintended pregnancy and HIV transmission is important for women with HIV, but little is known about their contraceptive use, particularly under current antiretroviral therapy (ART) recommendations for treatment and prevention. METHODS The prevalence of contraceptive use and of dual protection was examined among 453 sexually active women with HIV aged 16-49 and enrolled in the Canadian HIV Womens Sexual and Reproductive Health Cohort Study in 2013-2015; multivariable logistic regression was used to identify correlates of use. Two definitions of dual protection were assessed: the World Health Organization (WHO) definition (consistent condom use alongside another effective method) and an expanded definition (consistent condom use or a suppressed HIV viral load alongside an effective method). RESULTS Overall, 73% of women used effective contraceptives, primarily male condoms (45%) or tubal ligation (19%). Eighteen percent practiced WHO-defined dual protection, and 40% practiced dual protection according to the expanded definition. Characteristics positively associated with contraceptive use were younger age, having been pregnant, being heterosexual, being unaware of ARTs HIV prevention benefits and having had partners of unknown HIV status (odds ratios, 1.1-6.7). Younger age and perceived inability to become pregnant were positively associated with both definitions of dual protection (1.04-3.3); additionally, WHO-defined dual protection was associated with perceiving HIV care to be women-centered and having had partners of unknown HIV status (2.0-4.1), and dual protection under the expanded definition was related to having been pregnant (2.7). CONCLUSIONS Future research should explore how sustained ART and broader contraceptive options can support womens sexual and reproductive health care needs.
